While we're at it, could I have some expert advice about HW/Col development in Proportions ?

(As I already wrote, I love this mod and think "standard" SE4 should be like it

)
1/ HW are full of Cult Centers right from the start, so is there stg to do to develop them until terraforming hi tech can add room for facilties ? I thought about scrapping SY or Resupply depot to make room for another CC or two but hesitates ...
2/ What's the "right path" to develop colonies ? They produce ridiculous amounts at start, I'm thinking putting Mineral Miners, some Research and then Cities, but this Last takes 6 yrs+ to produce !! I agree with Oleg that OutPosts and Towns/Small cities will be very welcome ...
Else I mostly use them for SY (in my HW system) or sat constrution, military facilities (training and other non-eco stuff..), but they don't really develop, even with liners importing pop regularly...
Is that pretty standard with Proportion mod ?
3/ Do AIs develop colonies or not ? I still have to run into one that does, so wonder ...
